Ukubuka konke komkhiqizo:
Intambo ye-alloy engu-4J29, eyaziwa nangokuthi i-Fe-Ni-Co sealing alloy noma intambo yohlobo lwe-Kovar, isetshenziswa kabanzi ezinhlelweni ezidinga i-glass-to-metal hermetic sealing. Iqukethe cishe i-29% nickel kanye ne-17% cobalt, okuyinika ukwanda kokushisa okulawulwayo okuhambisana eduze nengilazi ye-borosilicate. Lokhu kuyenza ifaneleke ukusetshenziswa kumashubhu kagesi, ama-vacuum relay, izinzwa ze-infrared, kanye nezingxenye ze-aerospace.

Ukwakheka Kwezinto:

• I-Nickel (Ni): ~29%

• I-Cobalt (Co): ~17%

• Insimbi (Fe): Ibhalansi

• Ezinye izakhi: inani elincane le-Mn, i-Si, i-C, njll.

Ukwanda Kokushisa (30–300°C):~5.0 x 10⁻⁶ /°C
Ubuningi:~8.2 g/cm³
Ukumelana:~0.42 μΩ·m
Amandla Okudonsa:≥ 450 MPa
Ukwelulwa:≥ 25%

Osayizi Abatholakalayo:

• Ububanzi: 0.02 mm – 3.0 mm

• Ubude: kuma-spool, ama-coil, noma ubude bokusika njengoba kudingeka

• Umphezulu: Okukhanyayo, okubushelelezi, okungenawo umoya

• Isimo: Kudonswe nge-Anneal noma kubanda

Izici Eziyinhloko:

• Ukuhambisana okuhle kakhulu kokunwetshwa kokushisa nengilazi eqinile

• Kuhle kakhulu ekuvaleni okungenawo umoya ezisetshenziswayo ze-elekthronikhi nezezindiza

• Ukushibilika okuhle kanye nokunemba okuphezulu

• Izakhiwo zikagesi ezizinzile ngaphansi kwezimo ezahlukahlukene zemvelo

• Izinketho zobubanzi obungokwezifiso kanye nokupakisha ziyatholakala

Izicelo Ezijwayelekile:

• Ama-relay e-vacuum kanye nama-relay avaliwe ngengilazi

• Ukupakisha amadivayisi e-infrared kanye ne-microwave

• Ukufakwa kwengilazi kuya kwensimbi kanye nezixhumi

• Amashubhu kagesi kanye nama-sensor lead

• Izingxenye ze-elekthronikhi ezivalwe nge-hermetic ezindiza kanye nokuzivikela

Ukupakisha Nokuthumela:

• Kutholakala ngama-spool epulasitiki, ama-coil, noma izikhwama ezivaliwe nge-vacuum

• Ukupakisha okulwa nokugqwala kanye nokulwa nomswakama okukhethwa kukho

• Ukuthunyelwa kuyatholakala ngendiza, olwandle, noma ngesivinini esikhulu

• Isikhathi sokulethwa: Izinsuku zokusebenza eziyi-7-15 kuye ngobuningi

Ukuphatha Nokugcina:
Gcina endaweni eyomile nehlanzekile. Gwema umswakama noma ukuchayeka kumakhemikhali. Kungadingeka ukunamathisela kabusha ngaphambi kokuvala ukuqinisekisa ukubopha okuhle kakhulu ngengilazi.
